4 Strategies to Effectively Right-Size Your Office Space

Right-sizing means matching your real estate footprint to actual attendance patterns rather than headcount on paper. For facilities directors and commercial real estate (CRE) leaders, it's become one of the highest-impact levers to simultaneously control costs while improving the workplace experience.
‍

Hybrid work has made the calculation harder, though. When Tuesday hits 85% occupancy and Friday drops below 20%, sizing by headcount almost guarantees you're overpaying most of the week. And cutting too aggressively can lead to other problems like overcrowded anchor days and frustrated employees.
‍

This guide covers how to assess your current footprint, the most effective strategies for right-sizing, and the data quality issues that determine whether those strategies truly work.

‍

How to Assess Your Current Footprint

Only 19% of building and facilities decision makers say their space planning runs mostly on data, according to a Butlr survey of 400 US leaders. More than a third rely on gut instinct.
‍

Headcount tells you who's on payroll, badge data tells you who walked through the door, and instinct tells you how the floor felt on a particular day. But none of those datapoints indicates how much space your organization uses in a normal week.
‍

Start by analyzing your building utilization for a typical week. There are core metrics give facilities and CRE leaders the clearest read on space use.

‍

Peak Occupancy

Peak occupancy is the highest headcount in the building at one time during a normal week. In a hybrid office, the peak usually falls on an anchor day like Tuesday or Wednesday. And even then attendance stays below total headcount. 
‍

To determine your peak occupancy, measure across four to six weeks rather than one. Then, use the 90th percentile day instead of the single highest reading. For example, if you count a week with a quarterly all-hands as normal demand, you'll size the office for a day that happens four times a year.
‍

As a benchmark, three quarters (73%) of organizations run between 61% and 100% full on their busiest days, according to CBRE's Americas Office Occupier Sentiment Survey. And two thirds (66%) report a typical day below 60%.

‍

Average Daily Utilization

Average daily utilization is the share of desks, rooms, and zones in use on a normal day. For instance, a meeting room booked for one hour and empty for the next seven would read as full at its peak. But it would run closer to 20% utilization across the day.
‍

Butlr's utilization benchmarks put healthy desk utilization between 60% and 70%, which leaves headroom for busy days without paying for empty ones. Compare your own number against that range floor by floor. A building-level average can hide a 40% floor behind a 90% one, and the 40% floor is the one you could consolidate.

‍

Cost per Occupied Seat

Cost per occupied seat is your total annual space cost divided by the average number of seats in use per day. So a seat that costs $5,000 a year at full use effectively costs about $14,300 at 35% utilization.
‍

This is the metric that often turns a facilities conversation into a finance discussion. A utilization percentage rarely moves a CFO, but a figure like $14,300 might. Track cost per occupied seat alongside peak occupancy, because chasing a lower cost per seat too aggressively creates crowding on your busiest days.

‍

Real World Example: Calculating Your Target Footprint

Say your company has 200 employees on a 3/2 hybrid schedule. Your target footprint depends on four inputs:

• Peak in-office attendance of 130 people rather than 200
• A target of 158 square feet per person at peak
• A 15% buffer for growth and collaboration space
• A target footprint of roughly 23,600 square feet (130 × 158 × 1.15)

In contrast, a headcount-based model would prescribe 31,600 square feet for all 200 employees. The difference comes to roughly 8,000 square feet, or about $400,000 a year at a fully loaded cost of $50 per square foot.
‍

Each person in the peak count adds about 180 square feet to the target, once you include the buffer. Overestimate peak attendance by just 10 people, and the target grows by about 1,800 square feet. Estimating the peak instead of measuring it gets expensive quickly.
‍

Let the size of the surplus guide your strategy. An extra thousand or two square feet is a case for reconfiguration, but a larger overage calls for flexible seating or a lease change.

‍

Strategies to Right-Size Your Office

Once you know how much excess space you're paying for, you can find the right strategy to address it. These four strategies run from lightest touch to heaviest, and the last one makes the first three work.

‍

1. Reconfigure and Zone Your Existing Layout

Reconfiguration changes how you use the space rather than how much of it you pay for. This approach works for organizations that have a moderate space surplus but that aren't ready or able to break a lease.
‍

The main tool here is activity-based zoning. Rather than assigning space by department or individual, you organize the floor by work mode, with zones for focused work, collaboration, social time, and phone or video calls. People move to the zone that fits the task instead of doing every kind of work at one assigned desk.

Utilization data often reveals a mismatch between what a floor offers and what people use it for. Private offices might go unused while phone booths run at capacity, or a 12-person boardroom might host a string of two-person calls.
‍

For example, a floor with 20 underused individual offices and 4 oversized conference rooms could be rezoned into 12 offices, two large meeting rooms, four huddle rooms, and a collaborative lounge. A change like that would recover around 1,500 square feet of functional capacity without touching the lease.
‍

But rezoning only works if you know which space types are overbuilt versus underbuilt. That takes utilization data at the room and zone level, since a building-wide number can't tell you a certain room is oversized.

‍

2. Adopt Flexible Seating Models

Flexible seating is ideal for hybrid organizations where employees split time between home and office. When nobody is in five days a week, a 1:1 ratio of desks to employees guarantees empty seats.
‍

Many organizations are moving this way already. In CBRE's 2025 Americas survey, only 25% of companies report using assigned seating alone, down from 40% in 2024 and 56% in 2023.
‍

Companies that move away from assigned seating choose among three models:

• Hot-Desking: Desks are first-come, first-served with no reservations. It's the simplest model to implement, but it can create friction on busy days when people arrive and have to search for a seat.
• Hoteling: Employees reserve desks in advance through a booking system. It's more structured than hot-desking and reduces day-of conflict, but it depends on people following through on bookings.
• Neighborhood Model: Teams get assigned zones, and individuals within each zone use shared desks. It balances team identity with space efficiency.

Using the neighborhood model and incorporating hoteling inside each zone offers a middle path. It avoids both the seat-hunting friction of pure hot-desking and the waste of fully assigned seating. Plus, teams keep a home base even when individual desks rotate.
‍

Whichever model you choose, you'll need to set a sharing ratio, or the number of employees per desk. More than half of the seat-sharing companies in the CBRE survey run ratios under 1.5:1 today, but 73% expect to pass 1.5:1 by 2027.
‍

Start conservatively and let your peak occupancy data show how far you can stretch. A ratio that outruns your busiest day sends employees home.

‍

3. Restructure or Consolidate Your Lease

Lease restructuring is worth considering for organizations with a large space gap or an upcoming lease event. It delivers the biggest savings of any strategy here because it reduces costs rather than rearranging what the lease covers.
‍

You can cut costs in three ways:

• Consolidate Floors or Buildings: This path addresses significant overcapacity. Consolidation has the highest savings potential, but it also brings disruption and change management costs, since teams move and routines break.
• Sublease Unused Space: A sublease is a better choice when you have excess capacity but aren't ready to fully exit. Subleasing offsets cost while preserving the option to grow back into the space. But it adds tenant management overhead and depends on demand in your market.
• Negotiate Lease Flexibility at Renewal: Build in contraction rights, shorter terms, or expansion options. Flexibility costs less to secure at the negotiating table than overcapacity costs to carry for a decade.

Consolidation is already the playbook for the largest companies. In the CBRE survey, 50% of companies with more than 10,000 employees report signing new leases to centralize into fewer buildings, compared to just 7% of all other respondents.
‍

Unlike a rezoned floor or a seating policy, a lease decision is hard to reverse. Sign for too little space and you'll pay peak market rates to expand or push employees into overcrowded anchor days. Sign for too much and the excess carries for the full term.
‍

Both mistakes start with an inaccurate target footprint. Verify the occupancy data before you negotiate the lease terms.

‍

4. Deploy Occupancy Sensors for Continuous Measurement

The three strategies above all require knowing how your space is used. A lease-sized decision needs measurement spanning weeks and months.
‍

Badge readers, booking software, and WiFi analytics each offer some version of this, though all of them miss part of the picture:

• Badge Data: Badge swipes tell you who entered the building but nothing about which floors filled up or which rooms went unused.
• Booking Systems: Reservations show intent rather than use. Ghost bookings, where a room or desk is reserved and nobody shows, inflate perceived demand unless check-ins are enforced.
• WiFi Analytics: These tools approximate device location, but they can't distinguish someone working at a desk from someone walking past it. Plus, they often double-count anyone carrying a phone and a laptop.

Thermal occupancy sensors close these gaps by continuously and anonymously measuring presence and headcount at the room and zone level. Butlr's battery-powered sensors detect body heat rather than images, so there are no cameras, personally identifiable information (PII), or device tracking.
‍

These sensors install in weeks rather than months. This quick deployment counts when a lease event is on the calendar and the decision needs a season of data behind it.

Common Mistakes Companies Make When Right-Sizing Office Spaces

Even with good data, right-sizing projects can go wrong:

• Sizing for the Average Day Instead of the Peak: If your average occupancy runs at 55% but Tuesday hits 85%, sizing for 55% means employees can't find a desk two days a week. Right-size for your common peak. Then handle rare spikes like all-hands with overflow tactics like converting lounge areas into temporary flex seating. A quarterly event shouldn't dictate the size of a 10-year lease.
• Relying on a Single Data Source: Every utilization tool has its own shortcoming, so layering them and knowing what each one can't see produces a more complete picture.
• Treating Right-Sizing as a One-Time Project: Attendance shifts with seasons, policy changes, and team growth, so a footprint that fits today drifts out of alignment as the organization changes around it. Continuous measurement turns right-sizing from a project into an ongoing capability, and it catches the drift before it becomes a lease problem.
• Cutting Space Without a Change Management Plan: Removing desks or floors without explaining the rationale, updating booking tools, and resetting workplace norms creates backlash. An employee who arrives at a full floor once may start booking desks just in case, inflating the booking data and making the space look busier than it is.

‍

Why Data Quality Determines Right-Sizing Outcomes 

Rezoning a floor, setting a sharing ratio, and signing a smaller lease all depend on accurate utilization data. Small errors get expensive at this scale. Confuse booked seats with occupied seats, and peak attendance will read 20 people high. This can shift the target footprint by thousands of square feet on a lease you'll hold for years.
‍

Common data sources vary widely in how close they get to real presence:

‍

Combining sources produces the best results, but they aren't equally trustworthy. Badge and booking data are proxies that can mislead on their own, while sensors measure presence directly. With sensor data as the baseline, you can see exactly how far your booking data runs from reality and correct for the gap.
‍

Privacy decides what's feasible just as much as accuracy does. In Butlr's survey of building and facilities decision makers, 92% say privacy concerns stand between them and the occupancy data they need. Among organizations with more than 1,000 employees, 69% call it a moderate-to-major obstacle.
‍

Cameras and device tracking are non-starters in many environments. Works councils block them, GDPR restricts them, and healthcare and higher education rule them out, since nobody wants cameras pointed at patients or students.
‍

Thermal sensing is often the only approach that satisfies both accuracy and compliance. In a hybrid office, that means you can measure utilization across every floor, meeting room, and phone booth without collecting images or tracking individual devices.
